# The `doVerbose` here is a nasty hack. We want to be
# able to say <package>.override { <some-generic-builder-arg> = <value };
# however due to the wrapping here, we'd need to capture all arguments
# and strip out `mkDerivation, stdenv, flags` and then inherit them all.
# OR define the keys and inherit them here (which is what we did with
# `doVerbose`. The better solution then is to try and drop those values
# from an @args caputre instead.
